Fine Grinding of Food Applications with the High-Density Bed Jet Mill ConJet®

In the food and luxury food sectors, micronization is one of the most important process steps. During the industrial manufacture of various products, for example soya flour, wheat flour (protein shifting), milk powder, gelling agents, cocoa powder, starches and sugar, grinding and classifying are both important parts of the process.

With our comprehensive experience and equally wide range of machines which includes fine impact mills, classifier- and jet mills...

The ConJet® high-density bed jet mill as a combination of a spiral jet mill with an integrated classifier wheel makes it possible to manufacture products reproducibly and with a steep particle size distribution. The adjustment of the fineness of grind is independent of the product load and is only done via the speed setting of the classifier wheel. As a result, the mill can be operated much more economically and efficiently with higher product loading. Another advantage compared to a conventional jet mill is that no minimum amount of product is required to carry out the grinding process. This means completely ground batches under the same conditions and maximum product yields, as only little residual material remains in the mill after a run.

The compact design ensures very good accessibility for easy and fast cleaning during product changes. Residue-free grinding and low buildup of product inside the machine make the ConJet® the ideal mill also for processing products from the food sector. For example, food dyes such as carmine or Allura Red AC with a target fineness of d90 < 6 µm can be produced with the ConJet® high-density bed jet mill. The ConJet® is also the suitable solution for the production of lactose, which is used in food base mixtures as a high-quality nutrient with a fineness of 97 % < 10 µm.
